怎么使用情态动词

任何句子都有时态或情态,使用情态动词时记住两点:

  • 它是时表词;
  • 它 + 动词原型;

疑问句型: 疑问词 + 时表词 + 主语 + 动词 + 宾语

陈述句句型:

- 主 + 谓 + /宾/直宾 + /宾补/间宾
- 主 + 系 + 表

主 = n(人/物)
谓 = 时态/情态动词 + 动词
系 = 时态/情态动词 + 系动词(be/is/am/are/was/were)
宾 = n/ajd/adv/介词短语/done
表 = n/ajd/adv/介词短语/done

造句步骤:
1. 是否有动词,有,则是主谓结构,没有,则是主系表结构;
2. 判断时态或情态动词

例1: 他正在吃 / 吃 / 吃了/ 将要吃 / 已经吃过了
1. 带动词,用主谓宾
2. 时态,be doing / do / did / be going to do / has done
3. 套用公式 主 + 谓(时态 + 动词) --> he + (be doing / does / did / eat / is going to do / has done) + eat
4. 时态与动词结合 --> he is eating / eats / ate / is going to eat / has eaten

例2:他 在北京/ 昨天在北京 / 将在北京 / 正在在北京 / 他已经在北京2年了了
1. 没有动词,用主系表
2. 时态: (do / did / be going to do / be doing / have done)  + be
3. 主 + 系 + 表: he is / was / is going to be / is being / has been in Beijing
